two worklists: for nodes whose locations are block edges with loop terminators
and another for nodes with all other locations.  We only dequeue from the loop
worklist when the other is empty.  Exploration of the graph is still in
reverse-BFS.

it so that comments won't foul up macro expansions.

comments due to Ted's crazy table.  However, that could be fixed, and it
does work with single-line ones :).

cleaner code.

Remove FileVarDecl and BlockVarDecl. They are replaced by VarDecl::isBlockVarDecl() and VarDecl::isFileVarDecl().

This is a fairly mechanical/large change. As a result, I avoided making any changes/simplifications that weren't directly related. I did break two Analysis tests. I also have a couple FIXME's in UninitializedValues.cpp. Ted, can you take a look? If the bug isn't obvious, I am happy to dig in and fix it (since I broke it).

Fix bug in terminator processing for uninitialized-values: simply ignore the terminator, don't reprocess it.

LiveVariables analysis now does a flow-insensitive analysis to determine what variables have their address taken; these variables are now always treated as being live.

The DataflowSolver now uses "SetTopValue()" when getting the initial value for the entry/exit block.

Bug fix in VisitChildren: Only visit the last statement in a StmtExpr and the RHS of a comma expression, as the other Stmts will be visited elsewhere in a CFGBlock.

in a block's terminator.  This expression is visited within a block, but it is accessed by the
terminator.  This is important to observe because for live-variables analysis the block-level
expression is live between the terminator and where the expression occurs in the block.  So far
this hasn't been an issue to not observe this because the block-level expression used in the
terminator is always the last one in the block, and we have never queried the liveness information
about this point (but before the terminator).
